Errors with NZBGet configuration

Hi there
I have installed NZBGet from official repository.
At present, issues are

  1. I’m getting error messages(https://imgur.com/dNL9p8K) like Could not create file /home/me/Downloads/NZBGet/tmp/readurl-1.tmp .
    Similar threads ref Q.no.1(https://www.reddit.com/r/usenet/comments/7b9zz3/nzbget_log_file_and_usenet_logging_information/) & this(https://www.reddit.com/r/usenet/comments/64slaa/nzbget_error_with_arch_linux/)

  2. After a reload, errors(https://imgur.com/vLwbEwO) like nzbget.conf(46): Invalid value for option "NzbDir" (/home/me/Downloads/NZBGet/nzb): could not read information for directory /home/me/Downloads/NZBGet/nzb: errno 13,
    Smililar thread #3(https://bbs.archlinux.org/viewtopic.php?pid=1889553#p1889553)

  3. nzbget.log, nzbget.lock files & dst i.e. destination directory not created by default.

I followed arch wiki(https://wiki.archlinux.org/title/NZBGet). How can I resolve this ?

Any help is appreciated. Thanks.
